KIRBY CORPORATION AND CONSOLIDATED SUBSIDIARIES
NOTES TO CONDENSED FINANCIAL STATEMENTS
(Unaudited)

(1) | BASIS FOR PREPARATION OF THE CONDENSED FINANCIAL STATEMENTS

The condensed financial statements included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and footnote disclosures, including significant accounting policies normally included in annual financial statements, have been condensed or omitted pursuant to such rules and regulations. It is suggested that these condensed financial statements be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

(2) | ACCOUNTING STANDARD ADOPTION

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in United States Generally Accepted Accounting Principles when it becomes effective. ASU 2014-09 is effective for the Company on January 1, 2017. Early application is not permitted. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of ASU 2014-09 on its ongoing financial reporting.

(3) | INVENTORIES

The following table presents the details of inventories as of June 30, 2014 and December 31, 2013 (in thousands):

|  | June 30, 2014 |  |  | December 31, 2013 |
Finished goods |  | $ | 127,195 |  |  | $ | 120,751 |
Work in process |  |  | 8,738 |  |  |  | 15,136 |
|  | $ | 135,933 |  |  | $ | 135,887 |

(4) | FAIR VALUE MEASUREMENTS

The accounting guidance for using fair value to measure certain assets and liabilities establishes a three tier value hierarchy, which prioritizes the inputs to valuation techniques used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little, if any, market data exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing the asset or liability.
7

The following table summarizes the assets and liabilities measured at fair value on a recurring basis as of December 31, 2013 (in thousands):

December 31, 2013: |  | Quoted Prices in Active Markets for Identical Assets (Level 1) |  |  | Significant Other Observable Inputs (Level 2) |  |  | Significant Unobservable Inputs (Level 3) |  |  | Total Fair Value Measurements |
Assets: |  |  |  |  |  |  |  |  |  |  |  |
Derivatives |  | $ | — |  |  | $ | — |  |  | $ | — |  |  | $ | — |
Liabilities: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Derivatives |  | $ | — |  |  | $ | 59 |  |  | $ | — |  |  | $ | 59 |
Contingent liabilities |  |  | — |  |  |  | — |  |  |  | 4,903 |  |  |  | 4,903 |
|  | $ | — |  |  | $ | 59 |  |  | $ | 4,903 |  |  | $ | 4,962 |

In connection with the acquisition of Allied Transportation Company (“Allied”) on November 1, 2012, Allied’s former owners were eligible to receive up to an additional $10,000,000 payable in 2013 through 2015, contingent on developments with the sugar provisions in the United States Farm Bill. The fair value of the contingent liability recorded at the acquisition date was $9,756,000. The fair value of the contingent liability was based on a valuation of the estimated fair value of the liability after probability weighting and discounting various potential payments. Payments of $5,000,000 were made in the 2014 and 2013 first quarters on the contingent liability. The increase in the fair value of the contingent liability of $97,000 for the three months ended March 31, 2014 was charged to selling, general and administrative expense. As of June 30, 2014, no Allied contingent liability was recorded and no further payments will be made.
In connection with the acquisition of United Holdings LLC (“United”) on April 15, 2011, United’s former owners were eligible to receive a three-year earnout provision for up to an additional $50,000,000 payable in 2014, dependent on achieving certain financial targets. The fair value of the contingent earnout liability recorded at the acquisition date was $16,300,000. The fair value of the earnout was based on a valuation of the estimated fair value of the liability after probability weighting and discounting various potential payments. The decrease in the fair value of the earnout liability for the three months and six months ended June 30, 2013 of $6,100,000 and $10,400,000, respectively, was credited to selling, general and administrative expense. No United earnout liability was recorded as of December 31, 2013 and June 30, 2014.
The estimated fair value of total debt outstanding at June 30, 2014 and December 31, 2013 was $628,258,000 and $710,377,000, respectively, which differs from the carrying amounts of $649,300,000 and $749,150,000, respectively, included in the consolidated financial statements. The fair value was determined using an income approach that relies on inputs such as yield curves. Cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities have carrying values that approximate fair value due to the short-term maturity of these financial instruments.
Certain assets are measured at fair value on a nonrecurring basis and therefore are not included in the table above. These assets are adjusted to fair value when there is evidence of impairment. During the six months ended June 30, 2014, there was no indication that the Company’s long-lived assets were impaired, and accordingly, measurement at fair value was not required.

(5) | DERIVATIVE INSTRUMENTS

The Company recognizes all derivative instruments at fair value in the balance sheet as either assets or liabilities. The accounting for changes in the fair value of a derivative instrument depends on the intended use of the derivative and the resulting designation, which is established at the inception date of a derivative. For derivative instruments designated as cash flow hedges, changes in fair value, to the extent the hedge is effective, are recognized in other comprehensive income until the hedged item is recognized in earnings. Hedge effectiveness is measured at least quarterly based on the cumulative difference between the fair value of the derivative contract and the hedged item over time. Any change in fair value resulting from ineffectiveness is recognized immediately in earnings.
8

Interest Rate Risk Management
From time to time, the Company has utilized derivative financial instruments with respect to a portion of its interest rate risks to achieve a more predictable cash flow by reducing its exposure to interest rate fluctuations. These transactions generally are interest rate swap agreements and are entered into with large multinational banks. On February 28, 2013, all of the Company’s outstanding interest rate swaps expired. These interest rate swaps, with a total notional amount of $200,000,000, were designated as cash flow hedges.
Foreign Currency Risk Management
From time to time, the Company has utilized derivative financial instruments with respect to its forecasted foreign currency transactions to attempt to reduce the risk of its exposure to foreign currency rate fluctuations in its transactions denominated in foreign currency. These transactions, which relate to foreign currency obligations for the purchase of equipment from foreign suppliers or foreign currency receipts from foreign customers, generally are forward contracts or purchased call options and are entered into with large multinational banks. During the 2014 first quarter, the Company’s remaining forward contract with a notional amount of $469,000 expired.

(6) | STOCK AWARD PLANS

The Company has share-based compensation plans which are described below. The compensation cost that has been charged against earnings for the Company’s stock award plans and the income tax benefit recognized in the statement of earnings for stock awards for the three months and six months ended June 30, 2014 and 2013 were as follows (in thousands):

| Three months ended June 30, |  | Six months ended June 30, |
| 2014 |  | 2013 |  | 2014 |  | 2013 |
Compensation cost |  | $ | 3,120 |  |  | $ | 2,927 |  |  | $ | 5,273 |  |  | $ | 5,061 |
Income tax benefit |  | $ | 1,182 |  |  | $ | 1,106 |  |  | $ | 1,998 |  |  | $ | 1,913 |

The Company has an employee stock award plan for selected officers and other key employees which provides for the issuance of stock options, restricted stock and performance awards. The exercise price for each option equals the fair market value per share of the Company’s common stock on the date of grant. The terms of the options granted prior to January 25, 2010 are five years and vest ratably over three years. Options granted on or after January 25, 2010 have terms of seven years and vest ratably over three years. No performance awards payable in stock have been awarded under the plan. At June 30, 2014, 2,535,165 shares were available for future grants under the employee plan and no outstanding stock options under the employee plan were issued with stock appreciation rights.

The Company has a director stock award plan for nonemployee directors of the Company which provides for the issuance of stock options and restricted stock. The director plan provides for the automatic grants of stock options and restricted stock to nonemployee directors on the date of first election as a director and after each annual meeting of stockholders. In addition, the director plan allows for the issuance of stock options or restricted stock in lieu of cash for all or part of the annual director fee at the option of the director. The exercise prices for all options granted under the plan are equal to the fair market value per share of the Company’s common stock on the date of grant. The terms of the options are ten years. The options granted to a director when first elected vest immediately. The options granted and restricted stock issued after each annual meeting of stockholders vest six months after the date of grant. Options granted and restricted stock issued in lieu of cash director fees vest in equal quarterly increments during the year to which they relate. At June 30, 2014, 559,881 shares were available for future grants under the director plan. The director stock award plan is intended as an incentive to attract and retain qualified independent directors.

(8) | SEGMENT DATA

The Company’s operations are classified into two reportable business segments as follows:
Marine Transportation — Marine transportation principally by United States flag vessels of liquid cargoes throughout the United States inland waterway system, along all three United States coasts, Alaska and Hawaii and, to a lesser extent, United States coastal transportation of dry-bulk cargoes. The principal products transported include petrochemicals, black oil, refined petroleum products and agricultural chemicals.
Diesel Engine Services — Provides after-market services for medium-speed and high-speed diesel engines, reduction gears and ancillary products for marine and power generation applications, and distributes and services high-speed diesel engines, transmissions, pumps and compression products, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, for the land-based pressure pumping and oilfield service markets.
The Company’s two reportable business segments are managed separately based on fundamental differences in their operations. The Company evaluates the performance of its segments based on the contributions to operating income of the respective segments, and before income taxes, interest, gains or losses on disposition of assets, other nonoperating income, noncontrolling interests, accounting changes, and nonrecurring items. Intersegment sales for the three months and six months ended June 30, 2014 and 2013 were not significant.

(11) | RETIREMENT PLANS

The Company sponsors a defined benefit plan for its inland vessel personnel and shore based tankermen. The plan benefits are based on an employee’s years of service and compensation. The plan assets consist primarily of equity and fixed income securities.
15

The Company’s pension plan funding strategy has historically been to contribute an amount equal to the greater of the minimum required contribution under ERISA or the amount necessary to fully fund the plan on an accumulated benefit obligation (“ABO”) basis at the end of the fiscal year. The ABO is based on a variety of demographic and economic assumptions, and the pension plan assets’ returns are subject to various risks, including market and interest rate risk, making an accurate prediction of the pension plan contribution difficult. Based on current pension plan assets and market conditions, the Company does not expect to make a contribution to its pension plan prior to December 31, 2014 to fund its 2014 pension plan obligations. As of June 30, 2014, no 2014 year contributions have been made.
The Company sponsors an unfunded defined benefit health care plan that provides limited postretirement medical benefits to employees who meet minimum age and service requirements, and to eligible dependents. The plan limits cost increases in the Company’s contribution to 4% per year. The plan is contributory, with retiree contributions adjusted annually. The plan eliminated coverage for future retirees as of December 31, 2011. The Company also has an unfunded defined benefit supplemental executive retirement plan (“SERP”) that was assumed in an acquisition in 1999. That plan ceased to accrue additional benefits effective January 1, 2000.
The components of net periodic benefit cost for the Company’s defined benefit plans for the three months and six months ended June 30, 2014 and 2013 were as follows (in thousands):

(12) | CONTINGENCIES

On March 22, 2014, a tank barge and towboat (the M/V Miss Susan), both owned by Kirby Inland Marine, LP, a wholly owned subsidiary of the Company, were involved in a collision with the M/S Summer Wind on the Houston Ship Channel near Texas City, Texas. The tank barge was damaged in the collision resulting in a discharge of intermediate fuel oil from one of its cargo tanks. Regardless of fault or cause, the Oil Pollution Act of 1990 (“OPA 90”) obligates the Company, as the owner of the source of the discharge, for removal costs and damages and imposes on the Company the obligation to advertise the claims process by which persons who have claims may submit claims to the Company. The U.S. Coast Guard and the National Transportation Safety Board have named the Company and the Captain of the M/V Miss Susan, as well as the owner and the pilot of the M/S Summer Wind, as parties of interest in their investigation as to the cause of the incident. Sea Galaxy Ltd is the owner of the M/S Summer Wind.
The Company and the owner of the M/S Summer Wind have filed actions in the U.S. District Court for the Southern District of Texas seeking exoneration from or limitation of liability relating to the foregoing incident as provided for in the federal rules of procedure for maritime claims. The two actions have been consolidated for procedural purposes since they both arise out of the same occurrence. The actions require all claimants other than OPA 90 claimants to file their claims in those actions by August 21, 2014. There is a separate process for making a claim under OPA 90. The Company is processing claims properly presented, documented and recoverable under OPA 90. The Company is named as a party in other lawsuits filed in connection with this incident which are currently stayed by orders entered into by the court in the limitation proceedings. The actions include allegation of business interruption, loss of profit, loss of use of natural resources and seek unspecified economic and compensatory damages. In addition, the Company has received claims from numerous parties claiming property damage and various economic damages. The Company has also been named as a defendant in a civil action by two crewmembers of the M/V Miss Susan, alleging damages under the general maritime law and the Jones Act. The Company expects that additional lawsuits may be filed and claims submitted. The litigation and claims process is ongoing and many of the claims and lawsuits filed have not specified the amount of damages sought, but the Company believes it has adequate insurance coverage for pollution, marine and other potential liabilities arising from the incident. In addition to the insurance, the Company believes it has accrued adequate reserves for the incident and does not expect the incident to have a material adverse effect on its business or financial condition.
17

The Company is also involved in various legal and other proceedings which are incidental to the conduct of its business, none of which in the opinion of management will have a material effect on the Company’s financial condition, results of operations or cash flows. Management believes that it has recorded adequate reserves and believes that it has adequate insurance coverage or has meritorious defenses for these other claims and contingencies.
The Company has issued guaranties or obtained standby letters of credit and performance bonds supporting performance by the Company and its subsidiaries of contractual or contingent legal obligations of the Company and its subsidiaries incurred in the ordinary course of business. The aggregate notional value of these instruments is $46,877,000 at June 30, 2014, including $8,256,000 in letters of credit and $38,621,000 in performance bonds. All of these instruments have an expiration date within five years. The Company does not believe demand for payment under these instruments is likely and expects no material cash outlays to occur in connection with these instruments.

For purposes of the Management’s Discussion, all net earnings per share attributable to Kirby common stockholders are “diluted earnings per share.” The weighted average number of common shares applicable to diluted earnings per share for the three months and six months ended June 30, 2014 and 2013 were as follows (in thousands):

| Three months ended June 30, |  | Six months ended June 30, |
| 2014 |  | 2013 |  | 2014 |  | 2013 |
Weighted average number of common stock - diluted |  |  | 56,869 |  |  |  | 56,529 |  |  |  | 56,826 |  |  |  | 56,493 |

The increase in the weighted average number of common shares for the 2014 second quarter and first six months compared with the 2013 second quarter and first six months primarily reflected the issuance of restricted stock and the exercise of stock options.
Overview
The Company is the nation’s largest domestic tank barge operator, transporting bulk liquid products throughout the Mississippi River System, on the Gulf Intracoastal Waterway, coastwise along all three United States coasts and in Alaska and Hawaii. The Company transports petrochemicals, black oil, refined petroleum products and agricultural chemicals by tank barge. As of June 30, 2014, the Company operated a fleet of 874 inland tank barges with 17.3 million barrels of capacity, and operated an average of 252 inland towboats during the 2014 second quarter. The Company’s coastal fleet consisted of 71 tank barges with 6.0 million barrels of capacity and 76 coastal tugboats. The Company also operates seven offshore barge and tug units transporting dry-bulk commodities in United States coastal trade. Through its diesel engine services segment, the Company provides after-market services for medium-speed and high-speed diesel engines, reduction gears and ancillary products for marine and power generation applications, distributes and services high-speed diesel engines and transmissions, pumps and compression products, and manufactures and remanufactures oilfield service equipment, including pressure pumping units, for the land-based pressure pumping and oilfield service markets.
For the 2014 second quarter, net earnings attributable to Kirby were $74,992,000, or $1.31 per share, on revenues of $628,054,000, compared with 2013 second quarter net earnings attributable to Kirby of $63,093,000, or $1.11 per share, on revenues of $563,908,000. For the 2014 first six months, net earnings attributable to Kirby were $137,238,000, or $2.40 per share, on revenues of $1,217,300,000, compared with 2013 first six months net earnings attributable to Kirby of $119,671,000, or $2.10 per share, on revenues of $1,122,693,000. The 2014 first quarter and six months results included $2,766,000 before taxes, or $.03 per share, of severance charges which were mainly reflected in the marine transportation results. In addition, the 2014 first quarter and first six months results included an estimated $.03 per share combined negative impact from delays and the cost of extra horsepower to navigate the heavy ice conditions on the upper inland river systems, and costs related to a March 22, 2014 incident in the Houston Ship Channel. The 2013 second quarter and first six months results included a $6,100,000 before taxes, or $.07 per share, and $10,400,000 before taxes, or $.11 per share, respectively, credit to selling, general and administrative expenses, resulting from a net decrease in the fair value of the contingent earnout liability associated with the April 2011 acquisition of United. The 2013 second quarter and first six months results also included an estimated $.03 per share negative impact from high water on the Mississippi and Illinois Rivers and the negative impact of the closure for repair of the Algiers Lock near New Orleans on the Gulf Intracoastal Waterway, net of certain revenue and cost recovery from contracts with terms that provide reimbursements for delays and increased costs.

Marine Transportation
For the 2014 second quarter and first six months, 73% of the Company’s revenue was generated by its marine transportation segment. The segment’s customers include many of the major petrochemical and refining companies that operate in the United States. Products transported include intermediate materials used to produce many of the end products used widely by businesses and consumers — plastics, fiber, paints, detergents, oil additives and paper, among others, as well as residual fuel oil, ship bunkers, asphalt, gasoline, diesel fuel, heating oil, crude oil, gas condensate and agricultural chemicals. Consequently, the Company’s marine transportation business is directly affected by the volumes produced by the Company’s petroleum, petrochemical and refining customer base.
The Company’s marine transportation segment’s revenues for the 2014 second quarter and first six months increased 8% and 6%, respectively, compared with the 2013 second quarter and first six months. The segment’s operating income for the 2014 second quarter and first six months increased 19% and 14%, respectively, compared with the operating income for the 2013 second quarter and first six months. The higher marine transportation revenues reflected continued strong demand across all inland marine transportation markets, petrochemicals, black oil, refined petroleum products and agricultural chemicals, along with continued favorable pricing trends. The Company’s inland petrochemical, black oil and refined petroleum products fleets achieved consistent tank barge utilization levels in the 90% to 95% range throughout the 2014 second quarter and first six months. The Company’s coastal marine transportation markets reflected continued strong demand with tank barge utilization levels in the 90% to 95% range throughout the 2014 second quarter and first six months, aided by the increased transportation of crude oil and natural gas condensate, colder weather in the Northeast that increased the demand for heating oil during the 2014 first quarter and continued success in expanding the coastal customer base to inland customers with coastal requirements.
During the 2014 second quarter and first six months, approximately 80% of marine transportation’s inland revenues were under term contracts and 20% were spot contract revenues compared with 75% term contracts and 25% spot contracts for the 2013 second quarter and first six months. The 2014 second quarter and first six months increase in term contract revenues was primarily due to increased volumes from term contract customers, thereby reducing equipment available for spot contract movements. The harsh winter weather conditions during the 2014 first quarter and portion of the second quarter that required more equipment to meet contract volumes also contributed to the higher term contract revenues. Inland time charters represented 56% and 57%, respectively, of the revenues under term contracts during the 2014 second quarter and first six months.
During the 2014 first and second quarters, approximately 80% and 85%, respectively, of the marine transportation’s coastal revenues were under term contracts and approximately 20% and 15%, respectively, were spot contract revenues compared with 75% term contracts and 25% spot contracts for the 2013 second quarter and first six months. The increase in term contract revenues reflected a combination of stronger demand for coastal tank barges, as well as extended delivery times due to the harsh winter weather during the 2014 first quarter that extended into April. Coastal time charters represented approximately 90% of the revenues under term contracts during the 2014 and 2013 second quarters and first six months.
Rates on inland term contracts renewed in the 2014 second quarter and first six months increased in the 3% to 5% average range compared with term contracts renewed in the second quarter and first six months of 2013. Spot contract rates in the 2014 first and second quarters, which include the cost of fuel, increased modestly compared with the prior quarters. Effective January 1, 2014, annual escalators for labor and the producer price index on a number of inland multi-year contracts resulted in rate increases on those contracts of approximately 1.7%, excluding fuel.
Rates on coastal term contracts renewed in the 2014 second quarter and first six months increased in the 7% to 9% average range compared with term contracts renewed in the 2013 second quarter and first six months. Spot contract rates, which include the cost of fuel, continued to improve during the 2014 second quarter and first six months and remained above contract rates.
20

The marine transportation operating margin was 25.4% for the 2014 second quarter compared with 23.0% for the 2013 second quarter, and 23.9% for the 2014 first six months compared with 22.2% for the 2013 first six months.
Diesel Engine Services
For the 2014 second quarter and first six months, 27% of the Company’s revenue was generated by its diesel engine services segment. For the 2014 second quarter and first six months, 51% and 50% of the diesel engine services revenue was generated from overhauls and service, 25% and 24% from manufacturing, and 24% and 26% from direct parts sales, respectively. The results of the diesel engine services segment are largely influenced by the economic cycles of the marine and power generation markets and the land-based pressure pumping and oilfield services industries.
Diesel engine services revenues for the 2014 second quarter and first six months increased 22% and 16%, respectively, and operating income decreased 4% and 6%, respectively, when compared with the second quarter and first six months of 2013. The 2013 second quarter and first six months results included a $6,100,000 before taxes and a $10,400,000 before taxes, respectively, credit to selling, general and administrative expenses, resulting from a net decrease in the fair value of the contingent earnout liability associated with the April 2011 acquisition of United. Excluding the credits, the increases were primarily attributable to an improvement in the sale and service of land-based diesel engines and transmissions, and a continued increase in the manufacture of oilfield service equipment, including pressure pumping units. Demand for the remanufacture of pressure pumping units remained steady throughout the 2014 second quarter and reflected an improvement over the 2013 second quarter and first six months. The marine diesel engine services market improved modestly, benefiting from major service projects for inland and coastal customers, as well as Gulf of Mexico and foreign offshore service vessels and drilling operators. The power generation market was stable, benefiting from major generator set upgrades and parts sales for both domestic and international power generation customers.
The diesel engine services operating margin for the 2014 second quarter was 8.4% compared with 10.7% for the 2013 second quarter. For the 2014 first six months, the operating margin was 8.3% compared with 10.3% for the first six months of 2013. The operating margin for the 2013 second quarter and first six months was positively impacted by the $6,100,000 and $10,400,000, respectively, benefit due to the reduction of the United contingent earnout liability noted above.
Cash Flow and Capital Expenditures
The Company continued to generate strong operating cash flow during the 2014 first six months, with net cash provided by operating activities of $251,408,000 compared with $269,275,000 of net cash provided by operating activities for the 2013 first six months. The 7% decrease was primarily from a $7,027,000 net decrease in cash flows from changes in operating assets and liabilities and a $33,470,000 decrease in provision for deferred income taxes, partially offset by $17,578,000 of higher net earnings. In addition, during the 2014 and 2013 first six months, the Company generated cash of $7,275,000 and $2,573,000, respectively, from proceeds from the exercise of stock options and $3,884,000 and $13,111,000, respectively, from proceeds from the disposition of assets.
For the 2014 first six months, cash generated and borrowings under the Company’s revolving credit facility were used for capital expenditures of $163,299,000, including $57,456,000 for inland tank barge and towboat construction, $26,909,000 primarily for progress payments on the construction of two 185,000 barrel articulated tank barge and 10000 horsepower tugboat units, one scheduled to be placed in service in mid to late 2015 and one in the first half of 2016, and $78,934,000 primarily for upgrading existing marine transportation equipment and facilities and diesel engine services facilities, as well as the final costs for the construction of two offshore dry-bulk barge and tugboat units delivered during 2013. The Company’s debt-to-capitalization ratio decreased to 23.0% at June 30, 2014 from 27.0% at December 31, 2013, primarily due to a decrease of $99,850,000 of outstanding debt, and an increase in total equity from net earnings attributable to Kirby for the 2014 first six months of $137,238,000, exercises of stock options, and the amortization of unearned equity compensation. As of June 30, 2014, the Company had $7,300,000 outstanding under its revolving credit facility, $142,000,000 outstanding under its term loan and $500,000,000 of senior notes outstanding.
21

During 2013 and early 2014, the Company signed agreements to construct 66 inland tank barges with a total capacity of 1,220,000 barrels and one inland towboat, all for delivery throughout 2014. Based on current commitments, steel prices and projected delivery schedules, the cost of the 66 inland tank barges and one inland towboat is approximately $130,000,000.
During the 2014 first six months, the Company took delivery of 39 new inland tank barges with a total capacity of approximately 450,000 barrels, retired 21 inland tank barges and returned five leased inland tank barges, reducing its capacity by approximately 420,000 barrels. As a result, the Company added a net 13 inland tank barges and approximately 30,000 barrels of capacity during the first half of 2014.
In January 2014, the Company signed an agreement to construct a 185,000 barrel coastal articulated tank barge and 10000 horsepower tugboat unit at a cost of approximately $75,000,000 for delivery in mid to late 2015. In April 2014, the Company exercised its option for the construction of a second 185,000 barrel coastal articulated tank barge and 10000 horsepower tugboat unit at a cost of approximately $75,000,000 for delivery in the first half of 2016.
In May 2014, the Company signed an agreement to construct 30 inland 10,000 barrel tank barges for delivery throughout the 2015 first half, and in June 2014 signed an agreement to construct three inland towboats for delivery in the 2015 second half. Based on current commitments, steel prices and projected delivery schedules, the cost of the 30 inland tank barges and three inland towboats is approximately $50,000,000.
In July 2014, the Company signed agreements to construct two 155,000 barrel coastal articulated tank barge and 6000 horsepower tugboat units at a combined cost of approximately $125,000,000 to $130,000,000, the first for delivery in the 2016 second half and second in the 2017 first half.
The Company projects that capital expenditures for 2014 will be in the $370,000,000 to $380,000,000 range, including approximately $140,000,000 for the construction of 66 inland tank barges and one inland towboat for delivery throughout 2014 and progress payments on 2015 inland tank barge and towboat construction, as well as approximately $105,000,000 in progress payments on the construction of two 185,000 barrel coastal articulated tank barge and 10000 horsepower tugboat units, and two 155,000 barrel coastal articulated tank barge and 6000 horsepower tugboat units. The balance of $125,000,000 to $135,000,000 is primarily capital upgrades and improvements to existing marine transportation equipment and facilities and diesel engine services facilities, as well as the final costs for the construction of two offshore dry-bulk barge and tugboat units delivered during 2013.
Outlook
Petrochemical and black oil inland tank barge utilization levels remained strong during the 2014 first six months in the 90% to 95% range. While the United States economy remains sluggish with consistently high unemployment levels, the United States petrochemical industry continues to see strong production levels for both domestic consumption and exports. Low priced domestic natural gas, a basic feedstock for the United States petrochemical industry, provides the industry with a competitive advantage against foreign petrochemical producers. As a result, United States petrochemical production remained strong throughout 2013 and the 2014 first six months, thereby producing increased marine transportation volumes of basic petrochemicals to both domestic consumers and terminals for export destinations. The black oil market also remained strong throughout 2013 and the 2014 first six months, primarily due to continued stable United States refinery utilization levels, aided by the export of refined petroleum products and heavy fuel oils. In addition, the black oil market reflected continued strong demand for the inland and coastal transportation of crude oil and gas condensate from shale formations in South Texas and inland transportation of Canadian, Bakken and Utica crude oil and gas condensate from the Midwest to the Gulf Coast, as well as the coastal transportation of Bakken crude oil and gas condensate along the East and West Coasts.
The United States petrochemical industry is globally competitive based on a number of factors, including a highly integrated and efficient transportation system of pipelines, tank barges, railroads and trucks, largely depreciated yet well maintained and operated facilities, and a low cost feedstock slate, which includes natural gas. Certain United States producers have announced plans for plant capacity expansions and the reopening of idled petrochemical facilities. The current production volumes from the Company’s petrochemical and refinery customers have resulted in the Company’s inland petrochemical, black oil and refined petroleum products tank barge utilization levels in the 90% to 95% range and increased production from current facilities, plant expansions or the reopening of idled facilities should drive feedstock and production volumes higher, in turn leading to higher tank barge utilization levels and higher term and spot contract pricing, which could be mitigated by additional tank barge capacity.

As of June 30, 2014, the Company estimated there were approximately 3,450 inland tank barges in the industry fleet, of which approximately 500 were over 35 years old and approximately 275 of those were over 40 years old. Given the age profile of the industry inland tank barge fleet, the expectation is that older tank barges will continue to be removed from service and replaced by new tank barges that will enter the fleet. With continued strong demand for inland petrochemical, refined petroleum products and black oil tank barges, the Company estimates that approximately 280 inland tank barges were ordered industry-wide during 2013 and early 2014 for delivery throughout 2014. Historically, 75 to 150 older inland tank barges are retired from service each year, with the extent of the retirements dependent on petrochemical and refinery production levels, crude oil and gas condensate movements and industry-wide tank barge utilization levels.
As of June 30, 2014, the Company estimated there were approximately 265 tank barges operating in the 195,000 barrel or less coastal industry fleet, the sector of the market in which the Company operates. The Company believes that very few, if any, coastal tank barges in the 195,000 barrel or less category were built during 2012 and 2013. During 2013, coastal tank barge utilization was consistently in the 90% range, improving to the 90% to 95% range during the 2014 first six months with continued success in expanding the coastal customer base to include inland customers with coastal requirements and increased coastal demand for the movement of crude oil and natural gas condensate. The Company announced in January 2014 the signing of an agreement to construct a 185,000 barrel coastal articulated tank barge and 10000 horsepower tugboat unit at a cost of approximately $75,000,000, with delivery anticipated for mid to late 2015. In April 2014, the Company exercised its option for the construction of a second 185,000 barrel coastal articulated tank barge and 10000 horsepower tugboat unit at a cost of approximately $75,000,000 with delivery anticipated for the first half of 2016. In July 2014, the Company signed agreements to construct two 155,000 barrel coastal articulated tank barge and 6000 horsepower tugboat units at a combined cost of approximately $125,000,000 to $130,000,000, the first for delivery in the 2016 second half and the second in the 2017 first half. The Company is also aware of ten announced coastal tank barge and tugboat units to be constructed by competitors for delivery in 2014, 2015 and 2016.
In the diesel engine services segment, with the stable drilling activity in the Gulf of Mexico and positive inland and coastal marine transportation markets, service activity levels for the marine diesel engine services market during the 2014 first six months reflected a modest improvement and is anticipated to reflect some modest softness due to seasonality during the 2014 third quarter. The power generation market should remain stable, benefiting from engine-generator set upgrades and parts sales for both domestic and international customers. The land-based diesel engine services market consists of manufacturing and remanufacturing of oilfield service equipment, including pressure pumping units, and the distribution and service of their components, which include high-speed diesel engines, transmissions and pumps, many of the same components used by marine customers. Currently, an estimated 18 million horsepower is employed in the North American pressure pumping business. As a result of excess pressure pumping horsepower in 2012 and 2013, new orders for pressure pumping units essentially stopped and the supply and distribution portion of the land-based market slowed. During the 2014 second quarter, the land-based diesel engine business results reflected an improvement in manufacturing and remanufacturing of oil service equipment and the Company anticipates a continued improvement in this market in the 2014 second half.
Results of Operations
The Company reported 2014 second quarter net earnings attributable to Kirby of $74,992,000, or $1.31 per share, on revenues of $628,054,000, compared with 2013 second quarter net earnings attributable to Kirby of $63,093,000, or $1.11 per share, on revenues of $563,908,000. Net earnings attributable to Kirby for the 2014 first six months were $137,238,000, or $2.40 per share, on revenues of $1,217,300,000, compared with $119,671,000, or $2.10 per share, on revenues of $1,122,693,000 for the 2013 first six months. The 2014 first six months results included a $2,766,000 before taxes, or $.03 per share, first quarter severance charge which was mainly reflected in the marine transportation results. In addition, the 2014 first six months included an estimated $.03 per share first quarter combined negative impact from delays and the cost of extra horsepower to navigate the heavy ice conditions on the upper inland river systems, and costs related to a March 22, 2014 incident in the Houston Ship Channel. The 2013 second quarter and first six months results included a $6,100,000 before taxes, or $.07 per share, and $10,400,000 before taxes, or $.11 per share, respectively, credit to selling, general and administrative expenses, resulting from a net decrease in the fair value of the contingent earnout liability associated with the April 2011 acquisition of United. The 2013 first six months included an estimated $.03 per share second quarter negative impact from high water on the Mississippi and Illinois Rivers and the negative impact of the closure for repair of the Algiers Lock near New Orleans on the Gulf Intracoastal Waterway, net of certain revenue and cost recovery from contracts with terms that provide reimbursements for delays and increased costs.

Marine transportation revenues for the 2014 second quarter and first six months increased 8% and 6%, respectively, when compared with the 2013 second quarter and first six months, reflecting continued strong utilization levels for both the inland and coastal markets and favorable pricing trends. For the 2014 and 2013 second quarters, the inland tank barge fleet contributed 67% and 70%, respectively, and the coastal fleet 33% and 30%, respectively, of marine transportation revenues. For the 2014 and 2013 first six months, the inland tank barge fleet contributed 68% and 69%, respectively, and the coastal fleet 32% and 31%, respectively, of marine transportation revenues. The Company’s inland petrochemical, black oil and refined products fleets achieved consistent tank barge utilization levels in the 90% to 95% range throughout the 2014 second quarter and first six months. The Company’s coastal marine transportation markets reflected continued strong demand with tank barge utilization levels in the 90% to 95% range throughout the 2014 second quarter and first six months, aided by increased transportation of crude oil and natural gas condensate, continued success in expanding the coastal customer base to inland customers with coastal requirements, and cold weather during the 2014 first quarter that increased the demand for the transportation of heating oil.
25

The petrochemical market, the Company’s largest market, contributed 48% of the marine transportation revenues for the 2014 second quarter and first six months, reflecting continued strong volumes from Gulf Coast petrochemical plants for both domestic consumption and to terminals for export destinations. Low priced domestic natural gas, a basic feedstock for the United States petrochemical industry, provides the industry with a competitive advantage against foreign petrochemical producers.
The black oil market, which contributed 24% of marine transportation revenues for the 2014 second quarter and 25% for the first six months, reflected continued strong demand, driven by steady refinery production levels, the export of refined petroleum products and fuel oils, and demand for crude oil and gas condensate transportation from the Eagle Ford shale formations in South Texas both along the Gulf Intracoastal Waterway with inland vessels and in the Gulf of Mexico with coastal vessels, and for the movement of Canadian, Bakken and Utica crude oil and gas condensate downriver from the Midwest to the Gulf Coast. The coastal fleet also moved Bakken crude from Albany, New York to Northeast refineries, and from the Columbia River to West Coast refineries, a movement that began in the 2013 fourth quarter.
The refined petroleum products market, which contributed 25% of marine transportation revenues for the 2014 second quarter and 24% for the first six months, reflected continued strong demand for the movement of products in the inland and coastal markets, benefiting from volumes from major customers and aided by the export of refined petroleum products and heavy fuel oils. The coastal refined products market was also driven by continued success in expanding the coastal customer base to inland customers with coastal requirements, as well as a cold winter in the Northeast that increased the demand for heating oil during the 2014 first quarter.
The agricultural chemical market, which contributed 3% of marine transportation revenues for the 2014 second quarter and first six months, saw strong demand for both domestically produced and imported products during the first quarter but was hindered by the slow transit times created by the harsh Midwest operating conditions throughout the first quarter. Strong demand continued through the months of April and May 2014.
For the second quarter of 2014, the inland operations incurred 2,117 delay days, 16% less than the 2,520 delay days that occurred during the 2013 second quarter, and 27% less than the 2,897 delay days that occurred during the 2014 first quarter. For the first six months of 2014, 5,014 delay days occurred, 10% more than the 4,569 delay days that occurred during the 2013 first six months. Delay days measure the lost time incurred by a tow (towboat and one or more tank barges) during transit when the tow is stopped due to weather, lock conditions or other navigational factors. Operating conditions during the 2014 second quarter were seasonally normal while operating conditions during the 2014 first quarter were challenging, as transit times along the Gulf Intracoastal Waterway were affected by numerous strong frontal systems and fog, as well as heavy ice conditions on the Illinois, upper Mississippi and upper Ohio Rivers for the majority of the first quarter. While the Company continued to operate on these rivers during the 2014 first quarter despite the heavy ice conditions, transit times were increased, and either additional horsepower was required or tow sizes were reduced. High water conditions on the Mississippi and Illinois Rivers during the entire 2013 second quarter, and the closure of the Algiers Lock located on the Gulf Intracoastal Waterway due to structural damage during the entire 2013 second quarter, created heavy congestion and multi-day delays in the New Orleans area and along the alternate route to the Mississippi River at the Bayou Sorrels and Port Allen Locks.
26

During the 2014 second quarter and first six months, approximately 80% of marine transportation’s inland revenues were under term contracts and 20% were spot contract revenues compared with 75% term contracts and 25% spot contract revenues for the 2013 second quarter and first six months. The 2014 second quarter and first six months increase in term contract revenues was primarily due to increased volumes from term contract customers, thereby reducing equipment available for spot contract movements. The harsh winter weather conditions during the 2014 first quarter and portion of the second quarter that required more equipment to meet contract volumes also contributed to the higher term contract revenues. Inland time charters, which insulate the Company from revenue fluctuations caused by weather and navigational delays and temporary market declines, represented 56% and 57%, respectively, of the revenues under term contracts during the 2014 second quarter and first six months compared with 58% and 57%, respectively, during the 2013 second quarter and first six months. The 80% term contract and 20% spot contract mix provides the inland operations with a predictable revenue stream.
During the 2014 first and second quarters, approximately 80% and 85%, respectively, of the marine transportation’s coastal revenues were under term contracts and approximately 20% and 15%, respectively, were spot contract revenues compared with 75% term contracts and 25% spot contracts for the 2013 second quarter and first six months. The increase in term contract revenues reflected a combination of stronger demand for coastal tank barges, as well as extended delivery times due to the harsh winter weather during the 2014 first quarter that extended into April. Coastal time charters represented approximately 90% of the revenues under term contracts during the 2014 and 2013 second quarters and first six months.
Rates on inland term contracts renewed in the 2014 second quarter and first six months increased in the 3% to 5% average range compared with term contracts renewed in the second quarter and first six months of 2013. Spot contract rates in the 2014 first and second quarters, which include the cost of fuel, increased modestly compared with the prior quarters. Effective January 1, 2014, annual escalators for labor and the producer price index on a number of inland multi-year contracts resulted in rate increases on those contracts of approximately 1.7%, excluding fuel.
Rates on coastal term contracts renewed in the 2014 second quarter and first six months increased in the 7% to 9% average range compared with term contracts renewed in the 2013 second quarter and first six months. Spot contract rates, which include the cost of fuel, continued to improve during the 2014 second quarter and first six months and remained above contract rates.
Marine Transportation Costs and Expenses
Costs and expenses for the 2014 second quarter and first six months increased 4% compared with the 2013 second quarter and first six months. Costs of sales and operating expenses for the 2014 second quarter and first six months increased 4% and 3%, respectively, compared with the second quarter and first six months of 2013.
The inland operations operated an average of 252 towboats during the 2014 second quarter, of which an average of 78 towboats were chartered, compared with 262 during the 2013 second quarter, of which an average of 79 towboats were chartered. During the 2014 first six months, the inland operations operated an average of 254 towboats, of which an average of 76 towboats were chartered, compared with 259 towboats operated during the 2013 first six months, of which an average of 76 were chartered. As demand increases or decreases, or as weather or water conditions dictate, such as the heavy ice conditions on the Illinois, upper Mississippi and upper Ohio Rivers that occurred in the 2014 first quarter, the Company charters-in or releases chartered towboats in an effort to balance horsepower needs with current requirements. The Company has historically used chartered towboats for approximately one-third of its horsepower requirements.
During the 2014 second quarter, the inland operations consumed 11.4 million gallons of diesel fuel compared to 11.1 million gallons consumed during the 2013 second quarter. The average price per gallon of diesel fuel consumed during the 2014 second quarter was $3.18 compared with $3.22 for the 2013 second quarter. For the 2014 first six months, the inland operations consumed 22.4 million gallons of diesel fuel compared to 22.1 million gallons consumed during the 2013 first six months. The average price per gallon of diesel fuel consumed during the 2014 first six months was $3.15 compared with $3.24 for the 2013 first six months. Fuel escalation and de-escalation clauses on term contracts are designed to rebate fuel costs when prices decline and recover additional fuel costs when fuel prices rise; however, there is generally a 30 to 90 day delay before the contracts are adjusted. Spot contracts do not have escalators for fuel.
27

Selling, general and administrative expenses for the 2014 second quarter and first six months increased 13% and 12%, respectively, compared with the 2013 second quarter and first six months reflecting salary increases effective April 1, 2014, higher incentive compensation and higher professional fees. In addition, the increase for the 2014 first six months reflected a first quarter severance charge of $2,215,000 and the 2013 first quarter included a $370,000 severance charge.
Marine Transportation Operating Income and Operating Margins
Marine transportation operating income for the 2014 second quarter and first six months increased 19% and 14%, respectively, compared with the 2013 second quarter and first six months. The operating margin was 25.4% for the 2014 second quarter compared with 23.0% for the 2013 second quarter. The operating margin for the 2014 first six months was 23.9% compared with 22.2% for the 2013 first six months. The higher operating income and operating margin was a reflection of continued high inland and coastal equipment utilization, leading to higher inland and coastal term and spot contract rates negotiated throughout 2013 and the 2014 first six months. The higher operating margin for the 2014 first six months was partially offset by the winter weather conditions experienced throughout the 2014 first quarter and the March 22, 2014 incident in the Houston Ship Channel.
Diesel Engine Services
The Company, through its diesel engine services segment, sells genuine replacement parts, provides service mechanics to overhaul and repair medium-speed and high-speed diesel engines, transmissions, reduction gears, pumps and compression products, maintains facilities to rebuild component parts or entire medium-speed and high-speed diesel engines, transmissions and entire reduction gears, and manufactures and remanufactures oilfield service equipment, including pressure pumping units. The Company primarily services the marine, power generation and land-based oil and gas operator and producer markets.
The following table sets forth the Company’s diesel engine services segment’s revenues, costs and expenses, operating income and operating margins for the three months and six months ended June 30, 2014 compared with the three months and six months ended June 30, 2013 (dollars in thousands):

Current assets as of June 30, 2014 increased 22% compared with December 31, 2013. Trade accounts receivable increased 12%, primarily a reflection of the increase in both the marine transportation and diesel engine services revenues for the 2014 second quarter compared with the fourth quarter of 2013. Other accounts receivable increased 172%, primarily due to an increase in insurance claim receivables related to the March 22, 2014 incident in the Houston Ship Channel. Inventory in the diesel engine services segment was unchanged but reflected a decrease in the 2014 first quarter primarily due to the sale of pressure pumping units built in late 2013 and sold in the 2014 first quarter, offset in the second quarter with the building of land-based inventory for anticipated increased business activity levels and parts for 2014 third quarter projects.
30

Property and equipment, net of accumulated depreciation, at June 30, 2014 increased 3% compared with December 31, 2013. The increase reflected $163,299,000 of capital expenditures for the 2014 first six months, more fully described under Capital Expenditures below, less $77,823,000 of depreciation expense for the first six months of 2014 and $4,204,000 of property disposals during the 2014 first six months.
Other assets at June 30, 2014 decreased 8% compared with December 31, 2013 primarily due to the amortization of intangibles other than goodwill and the amortization of deferred major maintenance dry-dock expenditures on ocean-going vessels, net of major maintenance dry-dock expenditures for the 2014 first six months.
Current liabilities as of June 30, 2014 increased 36% compared with December 31, 2013. Accounts payable increased 18%, primarily from increased shipyard accruals and business activity levels in the diesel engine services segment. Accrued liabilities increased 50%, primarily from an increase in claims payable resulting from the March 22, 2014 incident in the Houston Ship Channel, partially offset by payment during the 2014 first six months of employee incentive compensation accrued during 2013. Deferred revenues increased 82%, primarily reflecting increased advanced billings for diesel engine services and marine transportation customers.
Long-term debt, less current portion, as of June 30, 2014 decreased 13% compared with December 31, 2013, reflecting net payments of $33,850,000 on the revolving credit facility and payments of $66,000,000 on the term loan during the 2014 first six months.
Deferred income taxes as of June 30, 2014 increased 3% compared with December 31, 2013. The increase was primarily due to the 2014 first six months deferred tax provision of $14,413,000.
Other long-term liabilities as of June 30, 2014 decreased 29% compared with December 31, 2013. The decrease was primarily due to a $5,000,000 payment during the 2014 first quarter associated with the $10,000,000 contingent liability recorded at the acquisition date of Allied pertaining to developments with the sugar provisions in the United States Farm Bill. A $5,000,000 payment was also made during the 2013 first quarter.
Total equity as of June 30, 2014 increased 8% compared with December 31, 2013. The increase was primarily the result of $137,238,000 of net earnings attributable to Kirby for the first six months of 2014 and an increase in additional paid-in capital due to the excess of proceeds received upon exercise of stock options and the issuance of restricted stock over the cost of the treasury stock issued.
Long-Term Financing
The Company has $500,000,000 of unsecured senior notes (“Senior Notes Series A” and “Senior Notes Series B”) with a group of institutional investors, consisting of $150,000,000 of 2.72% Senior Notes Series A due February 27, 2020 and $350,000,000 of 3.29% Senior Notes Series B due February 27, 2023. The Company issued $82,500,000 of Senior Notes Series A and $192,500,000 of Senior Notes Series B on December 13, 2012, the proceeds of which were used to fund the acquisition of Penn Maritime Inc. The Company issued $67,500,000 of Senior Notes Series A and $157,500,000 of Senior Notes Series B on February 27, 2013, the proceeds of which were used to refinance $200,000,000 of floating rate senior notes due February 28, 2013, with the balance used to pay down the Company’s unsecured revolving credit facility. No principal payments are required until maturity. The Senior Notes Series A and Series B contain certain covenants on the part of the Company, including an interest coverage covenant, a debt-to-capitalization covenant and covenants relating to liens, asset sales and mergers, among others. The Senior Notes Series A and Series B also specify certain events of default, upon the occurrence of which the maturity of the notes may be accelerated, including failure to pay principal and interest, violation of covenants or default on other indebtedness, among others. As of June 30, 2014, the Company was in compliance with all Senior Notes Series A and Series B covenants and had $150,000,000 of Senior Notes Series A outstanding and $350,000,000 of Senior Notes Series B outstanding.
The Company has a $325,000,000 unsecured revolving credit facility (“Revolving Credit Facility”) with a syndicate of banks, with JPMorgan Chase Bank, N.A. as the administrative agent bank, with a maturity date of November 9, 2015. The variable interest rate spread varies with the Company’s senior debt rating and is currently 1.5% over the London Interbank Offered Rate (“LIBOR”) or 0.5% over an alternate base rate calculated with reference to the agent bank’s prime rate, among other factors (“Alternate Base Rate”). The commitment fee is currently 0.3%. The Revolving Credit Facility contains certain restrictive financial covenants including an interest coverage ratio and a debt-to-capitalization ratio. In addition to financial covenants, the Revolving Credit Facility contains covenants that, subject to exceptions, restrict debt incurrence, mergers and acquisitions, sales of assets, dividends and investments, liquidations and dissolutions, capital leases, transactions with affiliates and changes in lines of business. Borrowings under the Revolving Credit Facility may be used for general corporate purposes, the purchase of existing or new equipment, the purchase of the Company’s common stock, or for business acquisitions. As of June 30, 2014, the Company was in compliance with all Revolving Credit Facility covenants and had $7,300,000 of debt outstanding under the Revolving Credit Facility. The Revolving Credit Facility includes a $25,000,000 commitment which may be used for standby letters of credit. Outstanding letters of credit under the Revolving Credit Facility were $6,079,000 as of June 30, 2014.
31

The Company has a credit agreement (“Term Loan”) with a group of commercial banks, with Wells Fargo Bank, National Association as the administrative agent bank, with a maturity date of July 1, 2016. The Term Loan provides for a $540,000,000 five-year unsecured term loan facility with a variable interest rate based on LIBOR or an Alternate Base Rate. The interest rate spread varies with the Company’s senior debt rating and is currently 1.5% over LIBOR or 0.5% over the Alternate Base Rate. The outstanding balance of the Term Loan is subject to quarterly amortization in increasing amounts and is prepayable, in whole or in part, without penalty. The Term Loan contains certain restrictive financial covenants including an interest coverage ratio and a debt-to-capitalization ratio. In addition to financial covenants, the Term Loan contains covenants that, subject to exceptions, restrict debt incurrence, mergers and acquisitions, sales of assets, dividends and investments, liquidations and dissolutions, capital leases, transactions with affiliates and changes in lines of business. As of June 30, 2014, the Company was in compliance with all Term Loan covenants and had $142,000,000 outstanding under the Term Loan, none of which was classified as current portion of long-term debt.
The Company had $200,000,000 of unsecured floating rate senior notes (“Senior Notes”) that were retired on February 28, 2013, the maturity date of the Senior Notes, with the proceeds from the Senior Notes Series A and Senior Notes Series B described above.
The Company has a $10,000,000 line of credit (“Credit Line”) with Bank of America for short-term liquidity needs and letters of credit, with a maturity date of June 29, 2015. The Credit Line allows the Company to borrow at an interest rate agreed to by Bank of America and the Company at the time each borrowing is made or continued. The Company had no borrowings outstanding under the Credit Line as of June 30, 2014. Outstanding letters of credit under the Credit Line were $869,000 as of June 30, 2014.
Interest Rate Risk Management
From time to time, the Company has utilized derivative financial instruments with respect to a portion of its interest rate risks to achieve a more predictable cash flow by reducing its exposure to interest rate fluctuations. These transactions generally are interest rate swap agreements and are entered into with large multinational banks. On February 28, 2013, all of the Company’s outstanding interest rate swaps expired. These interest rate swaps, with a notional amount of $200,000,000, were designated as cash flow hedges.
Foreign Currency Risk Management
From time to time, the Company has utilized derivative financial instruments with respect to its forecasted foreign currency transactions to attempt to reduce the risk of its exposure to foreign currency rate fluctuations in its transactions denominated in foreign currency. These transactions, which relate to foreign currency obligations for the purchase of equipment from foreign suppliers or foreign currency receipts from foreign customers, generally are forward contracts or purchased call options and are entered into with large multinational banks. During the 2014 first quarter, the Company’s remaining forward contract with a notional amount of $469,000 expired.
Capital Expenditures
Capital expenditures for the 2014 first six months were $163,299,000, including $57,456,000 for inland tank barge and towboat construction, $26,909,000 primarily for progress payments on the construction of two 185,000 barrel articulated tank barge and 10000 horsepower tugboat units, one scheduled to be placed in service in mid to late 2015 and one in the first half of 2016, and $78,934,000 primarily for upgrading existing marine transportation equipment and facilities and diesel engine services facilities, as well as the final costs for the construction of two offshore dry-bulk barge and tugboat units delivered during 2013. Capital expenditures for the 2013 first six months were $168,175,000, of which $106,297,000 was for construction of new inland tank barges and towboats, $12,333,000 for progress payments on the construction of the two offshore articulated dry-bulk barge and tugboat units completed in the 2013 second quarter, and $49,545,000 primarily for upgrading existing marine transportation equipment and facilities and diesel engine service facilities. Financing of the construction of the inland tank barges and towboats, coastal tank barges and tugboats, and the two offshore dry-bulk barges and tugboats was through operating cash flows and available credit under the Company’s Revolving Credit Facility.
32

During 2013 and early 2014, the Company signed agreements to construct 66 inland tank barges with a total capacity of 1,220,000 barrels and one inland towboat, all for delivery throughout 2014. Based on current commitments, steel prices and projected delivery schedules, the cost of the 66 inland tank barges and one inland towboat is approximately $130,000,000.
During the 2014 first six months, the Company took delivery of 39 new inland tank barges with a total capacity of approximately 450,000 barrels, retired 21 inland tank barges and returned five leased inland tank barges, reducing its capacity by approximately 420,000 barrels. As a result, the Company added a net 13 inland tank barges and approximately 30,000 barrels of capacity during the first half of 2014.
In January 2014, the Company signed an agreement to construct a 185,000 barrel coastal articulated tank barge and 10000 horsepower tugboat unit at a cost of approximately $75,000,000 for delivery in mid to late 2015. In April 2014, the Company exercised its option for the construction of a second 185,000 barrel coastal articulated tank barge and 10000 horsepower tugboat unit at a cost of approximately $75,000,000 for delivery in the first half of 2016.
In May 2014, the Company signed an agreement to construct 30 inland 10,000 barrel tank barges for delivery throughout the 2015 first half, and in June 2014 signed an agreement to construct three inland towboats for delivery in the 2015 second half. Based on current commitments, steel prices and projected delivery schedules, the cost of the 30 inland tank barges and three inland towboats is approximately $50,000,000.
In July 2014, the Company signed agreements to construct two 155,000 barrel coastal articulated tank barge and 6000 horsepower tugboat units at a combined cost of approximately $125,000,000 to $130,000,000, the first for delivery in the 2016 second half and second in the 2017 first half.
The Company projects that capital expenditures for 2014 will be in the $370,000,000 to $380,000,000 range, including approximately $140,000,000 for the construction of 66 inland tank barges and one inland towboat for delivery throughout 2014 and progress payments on 2015 inland tank barge and towboat construction, as well as approximately $105,000,000 in progress payments on the construction of two 185,000 barrel coastal articulated tank barge and 10000 horsepower tugboat units, and two 155,000 barrel coastal articulated tank barge and 6000 horsepower tugboat units. The balance of $125,000,000 to $135,000,000 is primarily capital upgrades and improvements to existing marine transportation equipment and facilities and diesel engine services facilities, as well as the final costs for the construction of two offshore dry-bulk barge and tugboat units delivered during 2013.
Funding for future capital expenditures is expected to be provided through operating cash flows and available credit under the Company’s Revolving Credit Facility.
Treasury Stock Purchases
The Company did not purchase any treasury stock during the 2014 first six months. As of August 6, 2014, the Company had approximately 2,685,000 shares available under its existing repurchase authorization. Historically, treasury stock purchases have been financed through operating cash flows and borrowing under the Company’s Revolving Credit Facility. The Company is authorized to purchase its common stock on the New York Stock Exchange and in privately negotiated transactions. When purchasing its common stock, the Company is subject to price, trading volume and other market considerations. Shares purchased may be used for reissuance upon the exercise of stock options or the granting of other forms of incentive compensation, in future acquisitions for stock or for other appropriate corporate purposes.
33

Liquidity
The Company generated net cash provided by operating activities of $251,408,000 during the 2014 first six months compared with $269,275,000 generated during the first six months of 2013. The 2014 first six months experienced a net increase in cash flows from changes in operating assets and liabilities of $3,218,000 compared with a net increase in the 2013 first six months of $10,245,000.
Funds generated from operations are available for acquisitions, capital expenditure projects, common stock repurchases, repayments of borrowings, and for other corporate and operating requirements. In addition to net cash flow provided by operating activities, the Company also had available as of August 5, 2014, $318,952,000 under its Revolving Credit Facility and $9,131,000 available under its Credit Line.
Neither the Company, nor any of its subsidiaries, is obligated on any debt instrument, swap agreement, or any other financial instrument or commercial contract which has a rating trigger, except for pricing grids on its Revolving Credit Facility and Term Loan.
The Company expects to continue to fund expenditures for acquisitions, capital construction projects, common stock repurchases, repayment of borrowings, and for other operating requirements from a combination of available cash and cash equivalents, funds generated from operating activities and available financing arrangements.
The Revolving Credit Facility’s commitment is in the amount of $325,000,000 and expires November 9, 2015. As of June 30, 2014, the Company had $317,700,000 available under the Revolving Credit Facility. The Senior Notes Series A and Senior Notes Series B do not mature until February 27, 2020 and February 27, 2023, respectively, and require no prepayments. The outstanding balance of the Term Loan is subject to quarterly amortization in increasing amounts and is prepayable, in whole or in part, without penalty.
There are numerous factors that may negatively impact the Company’s cash flow in 2014. For a list of significant risks and uncertainties that could impact cash flows, see Note 12, Contingencies in the financial statements, and Item 1A — Risk Factors and Note 14, Contingencies and Commitments, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. Amounts available under the Company’s existing financial arrangements are subject to the Company continuing to meet the covenants of the credit facilities as described under “Long-Term Financing” above and in Note 6, Long-Term Debt, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
The Company has issued guaranties or obtained standby letters of credit and performance bonds supporting performance by the Company and its subsidiaries of contractual or contingent legal obligations of the Company and its subsidiaries incurred in the ordinary course of business. The aggregate notional value of these instruments was $46,877,000 at June 30, 2014, including $8,256,000 in letters of credit and $38,621,000 in performance bonds. All of these instruments have an expiration date within five years. The Company does not believe demand for payment under these instruments is likely and expects no material cash outlays to occur in connection with these instruments.
All marine transportation term contracts contain fuel escalation clauses, or the customer pays for the fuel. However, there is generally a 30 to 90 day delay before contracts are adjusted depending on the specific contract. In general, the fuel escalation clauses are effective over the long-term in allowing the Company to recover changes in fuel costs due to fuel price changes. However, the short-term effectiveness of the fuel escalation clauses can be affected by a number of factors including, but not limited to, specific terms of the fuel escalation formulas, fuel price volatility, navigating conditions, tow sizes, trip routing, and the location of loading and discharge ports that may result in the Company over or under recovering its fuel costs. Spot contract rates generally reflect current fuel prices at the time the contract is signed but do not have escalators for fuel.
During the last three years, inflation has had a relatively minor effect on the financial results of the Company. The marine transportation segment has long-term contracts which generally contain cost escalation clauses whereby certain costs, including fuel as noted above, can be passed through to its customers. Spot contract rates include the cost of fuel and are subject to market volatility. The repair portion of the diesel engine services segment is based on prevailing current market rates.

Item 3. | Quantitative and Qualitative Disclosures about Market Risk

The Company is exposed to risk from changes in interest rates on certain of its outstanding debt. The outstanding loan balances under the Company’s bank credit facilities bear interest at variable rates based on prevailing short-term interest rates in the United States and Europe. A 10% change in variable interest rates would impact the 2014 interest expense by $64,000 based on balances outstanding at December 31, 2013, and would change the fair value of the Company’s debt by approximately 1.3%.

Item 4. | Controls and Procedures

The Company’s management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has evaluated the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) as of June 30, 2014. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that, as of June 30, 2014, the disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. There were no changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2014 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
